SPECIFICATION fOrmngpaIt 0f Lettel'S Pielt N0. l687,*(141, datedNOYember19, 1901. Application filed July 1,1901vl Serial No. 66,6;11. `(Nomodel.)

T0 all whom t may concern,.-

Be it known that I, WILLIAM L. LOGAN, a citizen of the United StatesfofAmerica, residing at Oxford, in the county ofDoddridge and State of WestVirginia, have invented certain new and useful Improvements in Valves,of which the following is a specification, reference being had thereinto the ac` companying drawings.

This invention relates to certain new and useful improvements in valves,and is parfticularly applicable for gas, water, steam, and the likewhere a high pressure is constantly maintained in the pipes.

The present invention has for its object the provision of novel meanswhereby the pressure-against the valve is entirely relieved;furthermore, to produce a perfect balancevalve that may be easily turnedto open'or close the ports.

The invention has for its'still further object to construct a valve'ofthe above-described character that will be extremelysimple inconstruction, strong, durable, and comparatively inexpensive tomanufacture; furthermore, one that will be highly efficient in itsoperation.

With the above and other objects in viewA the invention consists inthenovel combina- Ation and arrangement of parts to be hereinafter moremore fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, whereinlike numerals of reference indicate corresponding parts throughout theseveral views, and in which Figure 1 is a vertical sectional view of myimproved valve. Fig. 2 is a longitudinal sectional view thereof. Fig. 3is a top plan View of the valve. Fig. 4 is a side view of the valve.Fig. 5 is a front view thereof.

In the drawings the reference-numeral l indicates a valve-casing havingan inlet-port 2 andan outlet-port 3. Arranged in the valve-casing is atriangular-shaped wall 4, forming passage-ways 5 5, communicating withports 6 6, registering with the valve.

The reference-n umeral 7 indicates the valve, having a semisphericalseat 8, adapted to be arranged in the seat 9, formed in the valvecasing.The said valve 7 is further provided with upwardly-extending walls l0,which are adapted toopen and close the ports 6. In the upper portionofthe valve is formed a square recess ll to receive the square end l2 ofthe valve-stem 14, the latter extending through ,the screwfthreadedcollar l5, arranged in the valve-casing. The referencenumeral 16indicates,k a contracted outlet communicating with the outlet 3, leadingfrom the interior of the valve.

' The operation of my improved valve' is 'as follows: The high pressurewhich is usually ragainst the valve will be normally against thetriangular wall et, which will divide the pressure into the passage ways5 5 and the two ports 6. These ports being on each side of the valvewill tend to equalize the pressure and will assure a perfect balance ofthe valve that will make it very easy to turn in one direction or theother. As the valve is turned as shownrin dotted lines in Fig. 2 theports will be closed, and when turned in the reverse direction, as shownin full lines, the ports will be open. A stop may be arranged in theinterior of the valve to limit the movement thereof, if desired,although this does not constitutea part of my invention.

The many advantages obtained by the use of my improved device will bereadily apparent from the foregoing description, taken in connectionwith the accompanying drawings.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a valve, a valve-casing having an inlet-port and a contractedoutlet-port located opposite to each other in the valve-casing, a valveseated for rotation in the casing, said valve cut away on .both sidesand having a central opening, Va triangular wall varranged within thecasing in front of `the inlet forming two passage-ways communicatingwith inlet-ports leading to opposite sides of the valve, and means foroperating the valve, substantially as described.

2. In a valve, the combination of a valvecasing, a triangular wallarranged therein, a

IOO

suitable inlet and outlet port, a valve arranged in said casing, asemispherical valve-seat, and a Valve-stem, substantially as described.

3. In a valve, the combination of a casing having arranged therein twopassage-Ways communicating with the inlet-port, and a contractedoutlet-port, a valve having tWo upwardly-extendin g walls, asemisphericaiseat, and a stem arranged to said valve, substantiaily asdescribed.

4. In a Valve, the combination with a Valveeasing, a wail arranged insaid casing forming two passage-Ways communicating with the inlet-port,an outlet-port arranged in said casing, a valve, two Walls arranged insaid valve, and a semisphericai seat and stem, all parts being arrangedand operating substantially as described, and for the purpose set forth.

In testimony whereof I affix my signature in the presence of twoWitnesses.
